BUFFER.

Original application filed April 17, 1922, Serial No. 553,462, new Patent No. 1,647,766, dated November 1 1927. Divided and this application filed October 3, 1927. Serial No. 223,855.

This invention relates to a vehicle bufier particularly designed and intended for use with motor vehicles and having more" particular reference to the specific form of the 5 bumper bar and the means for connecting and reinforcing the bar at the ends thereof.

One of the principal objects of the'present invention is in the provision of improved means for connecting together the ends of a number of cross bars'which, when united, form a buffer of great strength, able to withstand front and side impacts without breaking or distortion.

A further object of the invention is to pro- 5 vide connecting elements at the ends of a buffer bar which are united and strengthened kind partly broken away in the center and with apin at one end shown in section.

This application is a division of original application No. 553,462, filed April 17, 1922,

which has become Patent No. 1,647 ,7 66 and the present application is directed to the partlcular manner of connecting the ends of a multiple bar .bufi'er.

laps and encloses the extremities of these bars, the present invention proposes a two piece hinged platewhich may be secured to 40 the ends of the bars, each plate being formed pin is inserted for connecting together and strgngthening the plates and the buffer at its en s.

Referring more particularly to the drawings, a plurality of bars 62 which are of a length to extend across the front offa vehicle, such as an automobile, at the ends of which are hinge plates 63 and 64 positioned on opposite sides of the bars 62 and connectedthereto by means of clamping bolts 69. The extremities of the plates .are formed with eyes or loops 65 and 66 arranged alternately and in line with each other so that a single 55 bolt or pin 67 may be inserted therethrough,

as above described, without departing from Instead of uniting the ends of a multiple bar by means of a single platewhich overwith a loop or eye through which a hingeduniting the plates, holding them together at the ends and materially strengthening and aligning the buffer, preventing the dislocation of the individual bars 62. a

The extremities of the pin 67 may be formed with heads 70 at one or both ends, and the plates 63 and 64am adapted to swing apart like a hinge when they are not attached to the cross bars. It is not necessary, howi j ever, that the hinges bethus assembled be- 65 fore application to the bars 62 as the plates may be attached separatel and the pin 67 thereafter inserted, as exp ained, the heads on the pin or at least one of them vbein formed after the pin is in place.

'As illustrated in the drawings, the plates are curved at the ends of the bars 62, the extremities of the bars being correspondingly curved to fit between the plates 63- and 64. This in itself adds strength and rigidity and affords a lateral bumper surface, but it should be understood that the plates may be applied to the straight extremities of a number of bars with the pin 67qconnecting them,

the scope of this'invention. i

I claim:

1. In a butler of the class described, a plurality of separate bars arranged in a single plane,'and attaching means comprising a two-piece hinged guard secured to and extendlng over the ends of the bars for conmeeting them to form a unitary impact member;-

. 2, In a buffer of the class described, a

a 9e pluraht of transverse impact membersand means or uniting the members at the ends,

said means comprising plates with eyes at the end and means including a pin insertable through the e es for connecting and strengthening the plates. 6 a I 3. ,In a butler of the class described, a: plurality of bars. arranged in a vertical plane, and means for connecting the bars together at their ends comprising opposite plates with eyelets projecting in alignment, and apin insertable through the eyelets for connecting the plates.

4. In a buffer of the class described, a plurality of separate bars, connecting means comprising plates having openings which register with eyelets at the ends of the bars, and connecting ins for uniting the bars and plate's through t e openings and the eyelets.

5. In a butler, the combination with I. 110

' plurality of separate transverse impact members, and means for uniting the impact members together at the ends, said means comprising pins and lates having alternate eyelets throu h whic the pins are insertedfor uniting t em.

6. A built-up bufl'er comprising a plurality of transverse bars curved at the ends,

and means for uniting the curved ends, said means comprising opposite. curved plates havin eyelets which are in alignment and are alternately disposed, and a connecting pin inserted through the eyelets for holding the plates together.

7. In a buffer, a plurality of separate bars,

a pair of plates extending on opposite sides of the bars at each extremity thereof, means members into an independent unitary bumper bar.
